PromptGuard vs RedForge

PromptGuard is a security layer between an application and its LLM provider, inspecting requests before they reach the model. It describes 15 detectors across six layers for risks such as prompt injection, jailbreaks, PII, data exfiltration, toxicity, fraud, secrets, malware and tool injection. The product says it detects and redacts 43 PII types using reversible tokenization. Its SDK can automatically instrument supported LLM calls with one initialization call while leaving existing provider code unchanged. Listed providers include OpenAI, Anthropic, Gemini, Azure, Bedrock, Mistral, Cohere, DeepSeek, Groq, HuggingFace, Ollama and vLLM. Deployment options include managed cloud, hybrid self-hosting and air-gapped installations. In zero-retention mode, prompt and response content is not stored; default security events include a shortened preview and content hash. PromptGuard says customer prompts, completions and documents are not used to train, fine-tune or evaluate models. The Free tier is permanent and includes 20,000 scans a month, one API key, one project and 24-hour log retention. Paid plans include a 14-day money-back guarantee, not a trial.

RedForge is a free, open-source LLM security testing platform for red teaming and vulnerability scanning. It runs on Linux, through an API and as self-hosted software. The project lists more than 49 probes, full OWASP LLM Top 10 coverage and YAML probe additions without Python. Attack modules include PAIR, Crescendo multi-turn escalation, Skeleton Key, many-shot jailbreaking and GCG adversarial suffixes. Its mutation engine expands two payloads into 37 variants using encoding, Unicode, cognitive reframing and structural injection strategies. Provider adapters cover OpenAI, Anthropic, Google Gemini, AWS Bedrock, Azure OpenAI, Mistral, Ollama, HuggingFace and generic REST endpoints. Ollama runs locally without an API key. Scans create JSON, JSONL audit and failures reports, with HTML, Markdown and SARIF also available. Compliance reports cover NIST AI RMF, EU AI Act, ISO/IEC 42001, GDPR and OWASP LLM Top 10. RedForge is Apache 2.0 software for authorized use.
